Moyle

The Moyle is a gold and silver mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): Workings / Exploration = By August of 1934 two adits at a lower level had been driven, one 6 feet long and one 10 feet long. A third adit , 50 feet above the others, was 18 feet in length. Only rock from the lower workings had gold and silver values of interest.

Comment (Reference): Primary Reference = Capps, 1937

Comment (Geology): Geologic Description = This prospect is at the contact of Tertiary granodiorite and Cretaceous metasedimentary rocks and consists of bunches and stringers of pyritic iron-stained quartz. The quartz exhibits no well-defined trend. Samples assayed in 1934 are said to have gold and silver values ranging from $7.60 to $11.67 per ton (Capps, 1937). No additional information is available since the original description by Capps.

Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1), turbidite-hosted gold vein.

Comment (Deposit): Other Comments = Site is located in Kodiak National Wildlife Refuge.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Tertiary
